An asteroid spent roughly 60 years quietly shadowing Earth’s journey around the Sun before astronomers noticed it in 2025. Orbital calculations show 2025 PN7 has been locked in step with our planet since the 1960s, while archival images reveal that telescopes had photographed the faint object years before anyone realised what it was.

2025 PN7 is a tiny Sun-orbiting quasi-satellite whose 60-year relationship with Earth comes from orbital modelling, while precovery images now trace its measured history to 2013.
